Return the directory of the application. On unix systems (except MacOS X), it is not always possible to determine this correctly. Therefore, the APPDIR environment variable is returned first if it is defined. *

usage: dbGetDataBinary db column asChars pbuffer plen. Returns binary data to given buffer (that must be deallocated using wxcFree). The return length is wxSQL_NULL_DATA if NULL data was encountered. If asChars is True, the data is returned as characters, true binary data is than returned as a string of hex values (3E002C...).*

InputSink

Create an event driven input stream. It is unsafe to reference the original inputStream after this call! The last parameter bufferLen gives the default input batch size. The sink is automatically destroyed whenever the input stream has no more input.

Sort items in a list control. Takes a closure that is called with a CommandEvent where the Int is the item data of the first item and the ExtraLong the item data of the second item. The event handler should set the Int to 0 when the items are equal, -1 when the first is less, and 1 when the second is less. *
